Definitions

  • the invention relates to a method for the production of a self-luminous body, in which a fluorescent and/or phosphorescent layer is made to produce light, using a medium that emits a decay radiation, as well as to such a self-luminous body and a use of the same.
  • Self-luminous bodies of the stated type are fundamentally known and are sold by the applicant, for example, under the trade name “trigaligh.”
  • a layer of zinc sulfide (ZnS) is made to light up by means of tritium gas.
  • the self-luminous bodies of the aforementioned type are therefore also known as “tritium gas lights.”
  • the task of the invention is accomplished by means of a method for the production of self-luminous bodies, comprising the steps:
  • a self-luminous body comprising a housing composed of at least two housing parts, having a depression in at least one of the housing parts, which are connected with one another in gas-tight manner and enclose a cavity, wherein at least one feeder opening to the cavity is provided, which opening extends from the outside into the cavity and is closed and welded in gas-tight manner, and wherein a layer of a fluorescent and/or phosphorescent substance that can be excited to produce light, by means of decay radiation, and a medium that emits decay radiation for a substance that can be excited to produce light are disposed in the cavity.
  • self-luminous bodies having practically any desired shape, particularly also planar self-luminous bodies, also having a slight thickness in relation to their surface area, can be produced.
  • the light-emitting surface can furthermore be well structured. In this way, any desired luminous letters, numbers, symbols or other geometric surfaces, among others, can be implemented.
  • the self-luminous body produced in this manner can particularly be used as a watch crystal or as the face of a watch.
  • use as emergency lighting, a door sign, keyboard background light and the like are also conceivable.
  • the fluorescent and/or phosphorescent layer is produced by means of coating the housing part and/or the housing parts with an adhesive and subsequently applying a fluorescent and/or phosphorescent substance onto the adhesive layer.
  • a fluorescent and/or phosphorescent substance e.g. ZnS and/or ZnO
  • Coating of the housing part with the fluorescent and/or phosphorescent substance can take place by means of stamping, for example, as well as by means of sputtering.
  • the adhesive and/or the fluorescent and/or phosphorescent substance or the fluorescent and/or phosphorescent layer is/are applied to the housing part and/or the housing parts before production of the cavity.
  • the housing part and/or the housing parts can be selectively coated with adhesive and/or a fluorescent and/or phosphorescent substance, in comparatively simple manner.
  • the layers can be sprayed on or rolled on, particularly using masks. It is also conceivable, for example, to imprint the layers or to stamp them on.
  • the adhesive and/or the fluorescent and/or phosphorescent substance or the fluorescent/phosphorescent layer is/are introduced into the (finished) cavity by means of the at least one feeder opening.
  • luminous layers having a large area and particularly layers that are unstructured
  • the adhesive is applied to the housing and/or the housing parts before the cavity is produced, and the fluorescent and/or phosphorescent substance is introduced into the cavity by means of the at least one feeder opening.
  • selective wetting of the housing part and/or of the housing parts with adhesive is combined with simple deposition of the fluorescent and/or phosphorescent substance. In this way, a simple method for the production of structured luminous surfaces is obtained.
  • the fluorescent and/or phosphorescent substance can be introduced as a powder, as a gel, in the gas phase or as a solution.
  • the flow behavior of the stated substance can be improved by means of providing a micro-structure or nano-structure.
  • Advantageous possibilities for applying the fluorescent and/or phosphorescent substance to the housing parts are sputtering, vapor-depositing, spraying, rolling or spin-coating it on.
  • the depression is produced in the housing part by means of mechanical working (e.g. milling, ultrasound drilling) or using ion-beam removal, laser-beam removal, powder blasting or chemical etching. All these methods allow production of a depression within the scope of a proven production process, which thereby takes place in controlled manner.
  • a mask is disposed between the housing parts or on them.
  • the mask can also be disposed between the fluorescent and/or phosphorescent layer and at least one housing part.
  • the fluorescent and/or phosphorescent layer is combined with a structured mask, which allows the light produced to partially pass through, or partially reflects or absorbs it.
  • the housing parts as well as, if applicable, the mask are connected with one another by means of fusion bonding, for example at temperatures of 700-800° C.
  • the boundary surfaces of the connected parts are held together by means of van der Waals' forces.
  • the housing parts and, if applicable, the mask are connected with one another by means of anodic bonding, for example at temperatures of 350-450° C.
  • a chemical bond is initiated at the boundary surfaces of the parts to be connected, by means of electrical attraction forces, in other words by applying an electrical voltage.
  • the at least one feeder opening is welded shut using a laser and/or a gas flame. In this way, it is possible to close the feeder opening without the aid of additional substances.
  • methods for welding glass parts, using a laser are known as such, for example from EP 1 741 510 A1.
  • the self-luminous body is implemented using means that are proved in connection with tritium gas lights, so that great reliability of the self-luminous body can also be assumed.
  • phosphoric acid H 3 PO 4
  • zinc sulfide ZnS
  • zinc oxide ZnO
  • phosphoric acid as such does not have any excessive adhesion properties, and only forms an adhesive layer in combination with zinc sulfide (ZnS) and/or zinc oxide.
  • the adhesive which is present in the form of phosphoric acid, can thereby be applied in very differentiated manner, thereby making it possible to produce fine structures.
  • the phosphoric acid can be applied using the ink-jet printing method.
  • a mixture of phosphoric acid (H 3 PO 4 ) and zinc sulfide (ZnS) and/or zinc oxide (ZnO) is applied as the fluorescent/phosphorescent layer.
  • a substance that is adhesive in and of itself is therefore applied to the housing part and/or the housing parts.
  • This variant is therefore particularly suitable for imprinting (for example using the calender printing method or stamping method).
  • At least one of the housing parts is provided with support elements disposed distributed over the surface area of the cavity, which elements extend in the direction of the other housing part, and if the housing parts are supported on one another by way of these support elements. In this manner, the housing parts are prevented from being deformed or bent, particularly excessively, relative to one another.
  • At least one of the two housing parts is connected with the support elements.
  • the support elements can be positioned well in the cavity. If the support elements are connected with both housing parts, tensile forces and shear forces can also be better transferred between them.
  • the housing is configured as a block or flat piece, particularly if the block or flat piece is formed by two essentially plate-shaped housing parts having a polygonal or elliptical or circular base surface, and if the sum of the heights of the two housing parts that are perpendicular to the base surface is less than the shorter side length or a minimal diameter or radius of the same. In this manner, the light-emitting surface area is relatively large in proportion to the volume of the self-luminous body.
  • a reflective coating is disposed on the side of the body that faces away from the observer side, thereby making it possible to approximately double the light generated toward the observer.

  • FIG. 4 a variant of a self-luminous body in the form of a warning sign.
  • the exemplary embodiments show possible embodiment variants of a self-luminous body, whereby it should be noted at this point that the invention is not restricted to the specifically shown embodiment variants of the same, but rather diverse combinations of the individual embodiment variants with one another are possible, and this variation possibility lies within the ability of a person skilled in the art of this technical field, because of the teaching for technical action provided by the present invention. Therefore all conceivable embodiment variants that are possible by combining individual details of the embodiment variant that is shown and described are also covered by the scope of protection.
  • FIG. 1 shows an intermediate stage in the production of a self-luminous body 101 .
  • FIG. 1 shows an exemplary housing part 2 (e.g. composed of glass or silicon) and a further housing part 3 (e.g. composed of glass or boron silicate) of a self-luminous body 101 in an exploded representation.
  • the method for production of the self-luminous body 101 will now be explained in greater detail using FIG. 1 .
  • the method comprises the steps:
  • the depression 1 can be milled into the housing part 2 , for example. It is also conceivable that the depression 1 is produced using an ion beam. Likewise, the grooves provided for the feeder openings 4 can also be milled or produced using an ion beam.
  • the depression 1 can be produced in one of the surfaces of at least one of the housing parts 2 , 3 that face one another, to form a cavity or part of a cavity.
  • other material removal methods such as laser removal methods, powder blasting, and the like can also be used for the production of the depression and/or of the feeder openings 4 .
  • a cavity having two feeder openings 4 is then formed by setting the housing part 3 onto the housing part 2 .
  • the housing part 3 can be glued onto the housing part 2 or welded to it.
  • a fluorescent/phosphorescent layer is produced on at least one delimitation wall of the cavity.
  • adhesive e.g. phosphoric acid H 3 PO 4
  • a fluorescent and/or phosphorescent substance e.g. zinc sulfide ZnS and/or zinc oxide ZnO
  • media from the series of zinc sulfite, zinc oxide or phosphoric acid as a substance that can be made to produce light, by a medium that emits decay radiation.
  • the adhesive and, subsequently, the fluorescent and/or phosphorescent substance that forms the fluorescent and/or phosphorescent layer is introduced into the cavity through one of the two feeder openings 4 .
  • one of the two feeder openings 4 can be connected with an inflow line, and the other feeder opening 4 can be connected with an outflow line.
  • Adhesive can be introduced into the cavity in the form of a liquid or in the form of a mist, by way of the inflow line, and excess adhesive can be carried away by way of the outflow line.
  • the fluorescent and/or phosphorescent substance can be introduced into the cavity and carried away from it, either by way of the same lines or by way of separate lines.
  • the fluorescent and/or phosphorescent substance can be introduced into the cavity in a solution or in the gas phase or as a powder or gel or as a polymer.
  • the adhesive layer is applied to the housing part 2 and/or the housing part 3 before the parts are joined together.
  • the housing part 2 and the housing part 3 are joined together, and subsequently, the fluorescent and/or phosphorescent substance is introduced by way of the feeder openings 4 .
  • This variant has the advantage that the adhesive can be applied very selectively, specifically using a mask, to the housing part 2 and/or the housing part 3 , for example sprayed on or rolled on.
  • the adhesive and/or the fluorescent and/or phosphorescent substance is/are imprinted or stamped on, and thereby selective wetting of the housing part 2 and/or of the housing part 3 with adhesive and/or the fluorescent and/or phosphorescent substance can be produced.
  • the selective adhesive application can take place, for example, in the form or letters, numbers, symbols or other geometric figures, or any desired surfaces, for example.
  • the fluorescent and/or phosphorescent substance is subsequently introduced into the cavity, it deposits on the wetted surfaces and also forms letters, numbers, symbols, etc.
  • the adhesive applied to the housing part 2 and/or the housing part 3 but rather also the fluorescent and/or phosphorescent substance is applied to the adhesive layer before the housing part 2 and the housing part 3 are joined together.
  • the fluorescent and/or phosphorescent substance itself has adhesive or adhering properties. Separate adhesive application can then be eliminated. For example, a mixture of phosphoric acid (H 3 PO 4 ) and zinc sulfide (ZnS) and/or zinc oxide (ZnO) can be applied directly.
  • the fluorescent and/or phosphorescent substance 7 can be applied to the housing part 2 , 3 or introduced into the cavity 5 as a powder, as a gel, in a gas phase or in solution, and, in addition to the methods already mentioned, can also be sputtered, vapor-deposited, sprayed, rolled on or applied by means of spin-coating.

  • the underside of the cavity 5 is equipped, over its full area, with a fluorescent/phosphorescent layer 7 that has been applied using an adhesive layer 8 .
  • the layers 7 and 8 can equally be disposed on the top side of the cavity 5 . Therefore at least a part of the surface 12 of the housing parts 2 , 3 that delimits a cavity 5 is coated with the fluorescent and/or phosphorescent substance 7 .
  • a light-impermeable or at least light-weakening mask 9 is disposed on the housing part 3 itself. Holes in the shape of the numbers 3 , 6 , 9 , and 12 are provided in this layer.
